Rainbow stackings of random edge‐colorings
Bulletin of the London Mathematical SocietyAbstractA rainbow stacking of ‐edge‐colorings of the complete graph on vertices is a way of superimposing so that no edges of the same color are superimposed on each other. We determine a sharp threshold for (as a function of and ) governing the existence and nonexistence of rainbow stackings of random ‐edge‐colorings .

Journal of Animal Ecology, EarlyView.Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Strong 3-Rainbow Indexes of Closed Helm Graphs
Indonesian Journal of CombinatoricsLet G be a nontrivial, edge-colored, and connected graph of order m≥3 where adjacent edges may have the same color. A tree T in graph G is called a rainbow tree if all the edges in T have different colors.

Rainbow triangles in three-colored graphs
Journal of Combinatorial Theory, Series B, 2017 Erdos and Sos proposed a problem of determining the maximum number F(n) of rainbow triangles in 3-edge-colored complete graphs on n vertices. They conjectured that F(n) = F(a)+ F(b)+F(c)+F(d)+abc+abd+acd+bcd, where a+b+c+d = n and a, b, c, d are as equal as possible. We prove that the conjectured recurrence holds for sufficiently large n. We also prove

The Carceral Shadow: Criminal Justice as a Determinant of Health and Challenges for Policymakers
The Milbank Quarterly, EarlyView.Policy Points The criminal justice system functions as a primary social determinant of health in the United States, generating disproportionate physical, psychological, and chronic health burdens on Black communities and other marginalized groups. Policing structural barriers—including qualified immunity, police union contracts, and municipal financing

Flap Anatomies and Victorian Veils: Penetrating the Female Reproductive Interior
Gender &History, EarlyView.ABSTRACT This article examines the reappearance in the early nineteenth century of anatomical flapbooks in the context of obstetrical education in Britain, America and France. It asks why liftable paper flaps were reintroduced at this time after their disappearance from medical atlases in the eighteenth century.

, 2019 In this thesis, we deal with rainbow colorings of graphs. We engage not with the rainbow connection number but with counting of rainbow colorings in graphs with k colors.

Rainbow Free Colorings and Rainbow Numbers for $x-y=z^2$
, 2023 An exact r-coloring of a set $S$ is a surjective function $c:S \rightarrow \{1, 2, \ldots,r\}$. A rainbow solution to an equation over $S$ is a solution such that all components are a different color.
